INTEGRATING-MACHINE.

Specification of Letters Patent.

Patented Oct. 30, 1906.

lAp'plication filed October 30, 1905. Serial No. 285,020.

To all whom it may concern:

Be it known that I, PHILIP J. DARLING- TON, a citizen of the United States, residing at 'Hinsdale, in the county of Dupage and State of Illinois, have invented a certain new and useful Improvement in Integrating-Machines, of which the following is a full, clear, concise, and exact description.

'My invention relates to a system of recordto keeping in which quantities or amounts are recorded by distances measured between terminal points on a record-blank and to a machine for automatically integrating, adding, and recording in figures the amounts thus 1 5 shown by a number of records.

While my invention will be useful for various purposes, it has been designed particularly to aid in computing shop costs or workmens wages upon the basis of time spent. In another application, Serial No. 285,021, filed October 30, 1905, I have described an improved time-recorder by which elapsed time is indicated upon a record card or blank by the distance between two marks, one of z 5 which indicates the time of starting and'the other the time of stopping work. By means of my present invention the amounts of time (or any other quantities capable of similar indication) shown by a number of such rec- 3o ord-blanks may be easily and quickly integrated or reduced to figures, added, and the sum totals indicated and recorded. Such a system will be especially valuable for quickly and accurately computing the entire time 3 5 spent upon a particular piece of work or by a.

particular workman, and the corresponding shop cost or wages due, from a number of separate time-cards showing the individual amounts.

I will describe my invention particularly b 're'ferenceto the accompanying drawings, illiistrating' the preferred form of machine, in which- Figure 1 is a elevation.

The same figures of reference indicate the same parts wherever shown. The form of machine illustrated is adapted to receive individual record-cards 3, each of which bears an indication of a particular amount or quantity. These cards are mtended to befed through the machmepne after another, and the machine is providedwith integratin and adding mechanism which is control ed by the record-marks on said cards, and thereby actuated to perform plan view, and Fig.2 a side the necessary calculations. In Fig. 2 one of the cards 3 is shown as having passed through the machine, and a portion of another card (the ends of which are broken away) is also shown in the act of passing through. Each card has two holes 4 5 punched therein, and it is the distance on the scale between these two holes which indicates the quantity (in this case elapsed time) to be integrated. These holes are offset withrespect to each other, so as to follow different parallel paths asthe card travels through the machine, and the two fingers 6 7 are provided upon the machine in such positions that as the card travels one of the holes therein will pass under one finger and the other hole under the other finger. Two drums 8 9 are provided at the ends of the machine, around which drums an endless belt 36 is passed. The cards are fed into the machine in position to rest upon the upper side of the lower lap of the belt and to be carried thereby around one of the drums, upon which the ends of the fingers 6 .7 normally rest. After leaving said drum 9 the cards are discharged in a tray 10.

The drum 9 is metallic and forms one terminal of two branch electric circuits 14 15, the other terminals of which are formed by the ends of the fingers 6.7. Said fingers are pivoted upon the frame of the machine and insulated therefrom and from each other,

and each card as it passes beneath said fingers is adapted to lift them from the drum to break the corresponding branch electric cir-- cuits. Said branch circuits are supplied with current from a battery 11 and include the energizing windings of solenoid-magnets 12 13, respectively.

As each card passes under the fingers =6f '7 both fingers are raised from the drum but as the card continues to travel the finger 6 drops through the hole 4 of the card (which is al .ways in advance of the other-hole 5) into contact with the drum 9, so that the branch circuit 14 containing magnet 12 is thereby closed. A further travel of the card brings the other hole-5 under the finger 7 to permit said finger in its turn to engage the drum and control the other branch circuit 15 containing the other magnet 13.

The successive actuations of the respective magnets 12 and 13 are thus brou ht about at intervals which bear a definite re ation to the longitudinal distance between the holes in the card and may be caused'to produce a. corduces a corresponding or proportionate rotation of the shaft 20 and .disk 19 and tends to transmit such corresponding or proportionate rotation to the disk 18 and spindle 17 of the counting-train. Said spindle 17, however is normally held against rotation by a pawl 22, engaging a ratchet-wheel 23, carried by said spindle, so that normally the frictiondisk 19 merely slips upon the disk 18 Without transmitting motion thereto. The awl 22 is pivoted at 24 and the end thereo' is normally held in engagement with the ratchetwheel 23; but the core of the solenoid-magnet 12 is connected with said awl, so that said magnet when excited ten s to rock the pawl out of engagement with said ratchetwheel and permit the counting-train to be advanced. The core of the other solenoidmagnet 13 is also connected with said pawl upon the opposite side of the pivot 24 there- 0 thus ten ing to oppose the effect of magnet 12 and keep the pawl in engagement with the ratchet-wheel to lock the counting-wheel against motion. The magnet 13 is adapted to overcome the effect of magnet 12, so that while both magnets are excited the effort exrted by magnet 13 will predominate, and

the counting train will thus be held locked.

This may be accomplished by winding the coil of magnet 13 with a greater number of ere-turns than the coil of magnet 12.

he pawl 22 is provided with a spring 37 for holding it in elther position to which it may be tilted, so that when once moved b gifignet 12 to release the counting-train it theteafterhe held in the release osition until positively moved back to the 00king position whether the magnet 12 remains excited or not. Similarly, when once tilted to the locking positionby magnet 13 said pawl will be held therein until I positively moved by the magnet 12.

shown in the drawin the count the spindle 17 of -train is provided with a ball- ,bearing or pivot 27 at its end, a bearing-plate 28 therefor being pressed against the same by springs 29. The end pressure thus exerted upon the spindle tends to maintain the disk 18 ressed against the driving-disk 19, so as to 'e kept in o erative relation thereto and to-co'mpensate or the Wear on said disks.

The totals indicated by the counting-train may be printed u on a result-record by the following means: in the machine illustrated the counting-train is mounted upon a movable framework 30, which is pivoted at 31 and arranged to be rocked about its pivot by a handle 32. A rec0rd-drum 33 is mounted below the counting-train and carries the result-record sheet 34, which may be in the form of a tape passing around said drum. The wheels of the counting-train are type- Wheels with raised figures, and an inked ribbon 35 is carried by rollers"mounted in the swinging frame 30, said ribbon being interposed between the type-wheels of the counting-train and the record-tape. The total indicated at any time upon the counting-train may thus be printed upon the tape 34 by simply depressing the handle 32 to swing the frame 30 downward and press the typewheels of the counting-train against the inked ribbon which marks the paper tape, the action being similar to a type-writer. Normally the swin ing frame is held up to keep the type-whee out of engagement with the tape 34 and the s indle 17 in alinement with the shaft 20 of t e driving mechanism. The operation of the machine is as follows: The drum 9 being started in rotation, the friction-disk 19 is driven and tends to drive the counting-train; but said counting-train is locked by the pawl 22 engaging the ratchetwheel 23, because both contact-fingers 6 7 are in engagement with the drum9 and both magnets 12 and 13 are excited the effort of magnet 13 predominating. The cards 3, bearing the punched records to be inte 'ated, are now fed upon the lower la s of the elt 36 and carried thereby around t e drum 9. As the forward edge of the card passes under the fingers 6 7 said fingers are lifted, breaking both circuits 14 and 15, so that both magnets 12 and 13 are deenergized and the pawl 22 still remains in engagement with theratchet to maintain the counting-train locked.

Now as the card continues its travel under the fingers 6 7 the hole 4 therein will be brou ht under the finger 6 and will permit said nger to fall into contact with the drum 9, thus closing circuit 14 and energizing the release-magnet 12. The circuit controlled by finger 7 through the retaining-magnet 13 being still open and said retaining-magnet unexcited, the pawl 22 will be tilted to release the ratohet-wheel and permit the counting-train to be driven by the friction-disk 19.

As the drum is now turned to advance the card, the counting-train will be driven throu h the agency of the friction-wheels 19 18, t e advance of the counting=train being in a definite ratio to the advance of the'card. This continues until the card has advanced far enough to bring the second hole 5 therein under the contact-finger 7, whereupon said finger, falling into contact with the drum 9, completes the circuit 15 through the retaining or lookin magnet 13. Said magnet, be-

ing excited, acts to tilt the pawl 22 back into 2: card that 5 passes beyond the end of the finger 7 the circuit 15 is again opened by said finger riding up on the card, but the pawl 22 is maintalned in its locking position by the spring 37. Then, finally, as the card leaves both of the fingers 6 7 both circuits 14 15 are again closed to excite both magnets 12 and 13, and

the effort of magnet 13 predominating, the pawl 22 will still remain in its locking position to prevent advance of the counting-train.

The same operations take place for each passes through the machine, so that the total amount which the countingtrain has advanced corresponds to the total of thedistances 4 5, measured on all the cards. In other words, the counting-train inte rates, adds, and indicates in figures the tota of all the quantities re resented by the records upon'all the cards which have passed through the machine. This total may be indicated u on the record-tape 34 by depressing the andle 32 to cause an impression of the printing-wheels against the tape through the interposedinkei ribbon. When a given lot of cards have been thus integrated and their records added and recorded, the

wheels of the counting-train may be returned to zero by running the machine backward or manually turning the counting-wheels to prepare the machine for a fresh start on the next lot of cards.

Any multiplying factor, such as the rate .per hour, can be introduced into the result by using a suitable ratio of gears between the drum-shaft 21 and. the driving-disk 19 of The-results may thus be cents.

Where in the speclficatlon or claims mentionfis made of the distance between the holes or marks of the card, I refer notnecessarily to the absolutely-straight-line distance from hole to hole, but rather to the distance which indicates the uantit the distance longitudinall along t e sca e. In the card shown one o the holes is nearer to the edge of the card. than the other; but it is obvious that the location of the hole may vary crosswise of the-scale without varying the indication thereby given. The effective distance is that which is si 'ficant, the longitudinal distance along t e scale between the points thereof indicated by the holes or other marks.

It will be understood that the invention herein described may be embodied in structures diflering widely from the particular therefore, desire to be understood as limiting myself to the precise form which has been chosen for the purposes of illustration; but
